Detailed Description

Embodiment

Hereinafter, a diaper according to an embodiment of the present utility model will be described with reference to the drawings. The following embodiments are examples, and the present utility model is not limited to these embodiments.

Fig. 1 is a perspective view of an adult pants-type disposable diaper (hereinafter, simply referred to as "diaper") according to an embodiment. In a diaper, a direction connecting a front body disposed to face an abdomen of a wearer and a rear body disposed to face a back is set as a longitudinal direction. The crotch portion disposed in the crotch (disposed opposite the crotch) of the wearer is located between the front body (one side in the longitudinal direction) and the rear body (the other side in the longitudinal direction) (the center in the longitudinal direction). In addition, when the diaper is worn on a wearer, the side facing the skin of the wearer is referred to as the skin surface side, and the opposite side to the skin surface side is referred to as the non-skin surface side. The direction connecting the skin surface side and the non-skin surface side is referred to as a thickness direction, and the direction perpendicular to either the longitudinal direction or the thickness direction is referred to as a width direction. The case of viewing from the thickness direction is referred to as planar view. The diaper 1 has a length along the longitudinal direction and a width along the width direction orthogonal to the longitudinal direction, and is worn on the crotch of a wearer. The term "direction" used herein refers to a direction that coincides with the front, rear, left, and right of the wearer when the diaper 1 is worn on the wearer. For example, the term "right-left direction" as used herein refers to a direction that coincides with the right-left direction of the wearer when the diaper 1 is worn on the wearer.

In the present embodiment, as an example of the absorbent article, a pants-type disposable diaper having a tubular structure with an opening into which the abdominal region of the wearer enters and a pair of left and right openings through which the left and right lower limbs of the wearer pass is exemplified, but the "absorbent article" in the present application is not limited to pants-type disposable diapers for adults. The term "absorbent article" as used herein includes pants-type disposable diapers for children. Further, there are various absorbent articles such as a belt-type disposable diaper having a tubular structure, which is formed by attaching a belt fixed to a portion of the sheet-like member that covers the crotch (pudendum) of the wearer from the front body over the back body, to a portion of the sheet-like member that is adjacent to the other end portion of the sheet-like member, and which can cover the abdomen and crotch.

The diaper 1 has: a crotch region 1B, wherein the crotch region 1B is a portion corresponding to a crotch portion that covers a pudendum (crotch) of a wearer in a worn state; a front body region 1F, the front body region 1F being a portion corresponding to a front body in a waist of a wearer and covering an abdomen side of the wearer; and a back region 1R, the back region 1R being a portion corresponding to the back in the waist of the wearer and covering the back side of the wearer. Here, the front body region 1F is located on the front side of the crotch region 1B, and the rear body region 1R is located on the rear side of the crotch region 1B. The diaper 1 in the present embodiment is a pants-type disposable diaper, and includes side seals SL and SR for joining widthwise ends of a front body region 1F and a rear body region 1R of an outer sheet to each other so as to form a torso surrounding portion 2D having a torso opening 2T. The left edge of the front body region 1F and the left edge of the rear body region 1R are joined to each other by a side seal SL, and the right edge of the front body region 1F and the right edge of the rear body region 1R are joined to each other by a side seal SR. Therefore, in the diaper 1, the trunk opening portion 2T is formed by the upper edge of the front body region 1F and the upper edge of the rear body region 1R. In the diaper 1, a left leg opening 2L is formed in a left portion of the crotch region 1B where the above-described joining is not performed, and a right leg opening 2R is formed in a right portion of the crotch region 1B. When the diaper 1 is worn with the left lower limb of the wearer inserted through the left lower limb opening 2L, the right lower limb of the wearer inserted through the right lower limb opening 2R, and the trunk of the wearer inserted through the trunk opening 2T, the front body region 1F is disposed on the abdomen side of the wearer, the rear body region 1R is disposed on the back side of the wearer, and the left lower limb opening 2L and the right lower limb opening 2R are fixed to the wearer's body in a state surrounding the thigh of the wearer. Since the diaper 1 is fixed to the body of the wearer in this manner, the wearer can freely move while wearing the diaper 1.

In the diaper 1, an absorber capable of absorbing and retaining liquid is mainly disposed around the crotch region 1B. In the diaper 1, in order to suppress formation of a gap which is a flow-out path of liquid between the diaper 1 and the skin of the wearer, a three-dimensional gather 3BL is provided in the left leg opening 2L surrounding the thigh of the left leg of the wearer, a three-dimensional gather 3BR is provided in the right leg opening 2R surrounding the thigh of the right leg of the wearer, and a waist gather 3R is provided in the trunk surrounding portion 2D surrounding the abdomen of the wearer. Leg gathers 3LL, 3LR are provided at positions surrounding the root portions of the legs of the wearer. The three-dimensional gathers 3BL, 3BR and the waist gather 3R are adhered to the skin of the wearer by the elastic force of the linear rubber. The leg gathers 3LL and 3LR prevent gaps from being formed between the root portions of the legs of the wearer and the diaper 1. Therefore, the discharged matter discharged from the private parts of the wearer hardly leaks out of the diaper 1 and is absorbed by the absorber of the diaper 1.

The diaper 1 can be used in combination with an inner pad (not shown). The inner pad is a substantially rectangular absorbent article provided with an absorber, and absorbs discharged liquid. In the case of using the diaper 1 and the inner pad in combination, the inner pad is placed on the skin surface side of the diaper 1 so as to abut against the discharge hole of the wearer. The discharged liquid is first absorbed by the inner pad, and only the discharged liquid which cannot be absorbed by the inner pad reaches the absorber of the diaper 1 and is further absorbed. Therefore, even when the amount of discharged liquid is large, leakage of discharged liquid from the diaper 1 can be prevented. In addition, when the amount of discharged liquid is small and the discharged liquid can be absorbed by the inner pad, only the inner pad needs to be replaced even if discharged liquid is generated, so that the intervention (nursing) cost can be reduced. In addition, the diaper 1 can be used for a long time.

Fig. 2 is an exploded perspective view of the diaper 1 of the embodiment. The diaper 1 has a cover sheet 4 ((an example of the "outer cover sheet" described herein)) and an inner cover sheet 5 (an example of the "inner cover sheet" described herein). The cover sheet 4 and the inner cover sheet 5 are substantially hourglass-shaped (gourd-shaped) sheets bonded together to form the outer surface of the diaper 1, and the front body region 1F-side end portion and the rear body region 1R-side end portion are the same shape. In a state of being worn on a wearer, the cover sheet 4 is laminated on the non-skin surface side of the wearer, and the inner cover sheet 5 is laminated on the skin surface side. Linear rubber for forming the waist gather 3R and the leg gathers 3LL, 3LR is provided between the cover sheet 4 and the inner cover sheet 5. Further, a band-shaped expansion member such as rubber can be appropriately selected instead of the linear rubber.

In order to suppress leakage of discharged material, the cover sheet 4 and the inner cover sheet 5 may be made of, for example, a nonwoven fabric made of a liquid impermeable thermoplastic resin. Here, examples of the liquid-impermeable thermoplastic resin include Polyethylene (PE) and polypropylene (PP).

The diaper 1 has a back sheet 6, an absorber 8, and a top sheet 9 laminated in this order on the wearer-side surfaces of the cover sheet 4 and the inner cover sheet 5. The back sheet 6 is a substantially rectangular sheet having a length extending from the front body to the rear body through the crotch in the longitudinal direction and a predetermined width in the width direction orthogonal to the longitudinal direction. The absorber 8 and the top sheet 9 are sheet-like members having a substantially rectangular appearance similar to the back sheet 6, and are sequentially laminated on the back sheet 6 in a state where the longitudinal direction matches the longitudinal direction of the back sheet 6. The back sheet 6 is a sheet made of a liquid impermeable thermoplastic resin for suppressing leakage of discharged material. The top sheet 9 is a sheet-like member disposed on the skin surface side of the wearer so as to cover the water absorbing surface of the absorber 8. Part or all of the top sheet 9 has liquid permeability. Therefore, in a state where the diaper 1 is worn, liquid discharged from the wearer is immersed in the absorbent body 8 through the topsheet 9 which may come into contact with the wearer's skin, where it is absorbed. Examples of the liquid-permeable sheet include woven fabrics, nonwoven fabrics, and porous films. In addition, the top sheet 9 may have hydrophilicity.

The absorber 8 has an absorbent core 8c and a core wrap sheet 7 (an example of a "water permeable sheet" of the present disclosure) that wraps the absorbent core 8 c. The absorbent core 8c has a structure in which a particulate absorbent resin (high molecular absorbent material) such as SAP (super absorbent polymer: super Absorbent Polymer) which is a hydrophilic polymer having a crosslinked structure capable of absorbing and retaining water is retained in the interstices of cellulose-based fibers such as pulp fibers, rayon fibers, and cotton fibers, and the like, and the fibers are hydrophilized with synthetic fibers such as polyethylene, polypropylene, and polyethylene terephthalate. When the absorbent core 8c absorbs liquid discharged from the wearer, the absorbent resin in the gaps held in the short fibers is swelled to hold the liquid in the short fibers. In the present embodiment, the absorbent core 8c is substantially hourglass-shaped with a narrowed central portion. The absorbent core 8c may take an appropriate shape according to the purpose. Examples of the shape of the absorbent core 8c include a rectangular shape, an elliptical shape, and various other shapes.

The core wrap sheet 7 is a thin liquid-permeable sheet, and by wrapping the absorbent core 8c with the core wrap sheet 7, the SAP of the absorbent core 8c is less likely to be mixed into other structures. In addition, the deformation of the absorbent core 8c is suppressed. The core wrap sheet 7 can be formed of pulp fibers, and as an example, a tissue can be used. The core wrap sheet 7 may be 1 sheet, or may be composed of 2 sheets, that is, an upper sheet disposed on the skin surface side of the wearer and a lower sheet disposed on the non-skin surface side of the wearer and wound around the side surface of the absorbent core and the skin surface side. When the core wrap sheet 7 is formed of 2 sheets, the width direction end portion of the upper side sheet may be wrapped with another sheet (for example, side sheets 10L and 10R, back sheet 6, and top sheet 9 described later). Further, the absorber 8 is wrapped with the back sheet 6 and the top sheet 9, and the shape of the body can be suppressed by these sheets, so that the core wrap sheet 7 may not be provided.

The back sheet 6, the absorber 8 and the top sheet 9 all extend from the front body region 1F to the back body region 1R. Therefore, when the back sheet 6, the absorber 8, and the top sheet 9 are laminated to cover the wearer's pudendum (crotch), the back sheet 6, the absorber 8, and the top sheet 9 are positioned on the wearer's abdomen side and back side, respectively, at both ends in the longitudinal direction. That is, the pudendum of the wearer is covered with the absorber 8 from the abdomen side to the back side of the wearer. Therefore, the discharged liquid is brought into contact with the absorber 8 via the top sheet 9 regardless of whether the wearer discharges the liquid to the outside in any one of the abdomen-down posture and the back-down posture.

The diaper 1 has elongated belt-shaped side panels 10L and 10R for forming the above-described three-dimensional gathers 3BL and 3 BR. The side sheets 10L and 10R are provided on the long side of the top sheet 9. The linear rubbers 10L1 and 10R1 are bonded to the side sheets 10L and 10R in the longitudinal direction. Thus, when the edge 4F4 of the cover sheet 4, which is the left edge of the front body region 1F, and the edge 4R4 of the cover sheet 4, which is the left edge of the back body region 1R, are joined to each other, and the edge 4F5 of the cover sheet 4, which is the right edge of the front body region 1F, and the edge 4R5, which is the right edge of the back body region 1R, are joined to each other, the side sheets 10L, 10R are pulled in the longitudinal direction by the contraction force of the linear rubbers 10L1, 10R1 and rise from the top sheet 9 along the folding lines 10L2, 10R2 (an example of the "standing line"). As a result, three-dimensional gathers 3BL and 3BR (described in detail below) are formed, which prevent liquid from flowing out through the left lower limb opening 2L and the right lower limb opening 2R. The bonding method of the edges 4F4 and 4R4, and the edges 4F5 and 4R5 is not particularly limited, and may be performed by heat sealing, high-frequency sealing, ultrasonic sealing, or the like, for example.

The diaper 1 further includes an end sheet 11F that is laminated on the wearer-side surface in the front region 1F of the cover sheet 4, and an end sheet 11R that is laminated on the wearer-side surface in the back region 1R of the cover sheet 4, with the backsheet 6, the absorber 8, the top sheet 9, and the side sheets 10L, 10R interposed therebetween. The end sheets 11F and 11R are elongated sheets that overlap the cover sheet 4 and the inner cover sheet 5 at one end side in the longitudinal direction of the top sheet 9. The end pieces 11F, 11R are non-water-impermeable nonwoven fabrics, and reinforce the cover piece 4 and the inner cover piece 5 mainly at the waist contact portion of the diaper 1. The end pieces 11F and 11R are coated with an adhesive, and bonded to the inner cover piece 5 with the adhesive. The end sheets 11F, 11R are disposed closer to the skin surface than the laminate formed by the back sheet 6, the absorber 8, the top sheet 9, and the side sheets 10L, 10R, and prevent the end portions of the laminate from directly contacting the skin surface to give the wearer discomfort (offensive feeling).

Fig. 3A and 3B are diagrams schematically showing a state in which the diaper 1 of the embodiment is developed and extended. Fig. 3A schematically shows an internal configuration in the case of the diaper 1 in an unfolded and elongated state as viewed from the left side. Fig. 3B schematically shows a plan view of the diaper 1 in an unfolded and extended state. In fig. 3B, the side panels 10L and 10R and the end panels 11F and 11R are not shown. One end side of the cover sheet 4 is folded back at folding back lines 4FF, 4RF shown in fig. 2. The above-described waist gather 3R is formed by bonding linear rubbers (linear rubbers) 4F1, 4F2 to the front region of the cover sheet 4 and bonding linear rubbers (linear rubbers) 4R1, 4R2 to the rear region of the cover sheet 4. The linear rubbers 4F1, 4F2 are provided in the order of the linear rubbers 4F1, 4F2 from the side of the folding line 4FF along the folding line 4FF forming the upper edge of the precursor region 1F when folded back. The linear rubbers 4R1 and 4R2 are also provided in the order of the linear rubbers 4R1 and 4R2 from the side of the folded back line 4RF along the folded back line 4RF that forms the upper edge of the back body region 1R when folded back, as with the linear rubbers 4F1 and 4F 2.

Therefore, the linear rubbers 4F1, 4F2 are provided on the cover sheet 4 in such an orientation that the longitudinal direction, which is the expansion and contraction direction, is the lateral direction of the diaper 1. The linear rubbers 4R1, 4R2 are provided on the cover sheet 4 in such a manner that the longitudinal direction, which is the extension and contraction direction, is the lateral direction of the diaper 1. Therefore, when the edge 4F4 and the edge 4R4 are joined to each other and the edge 4F5 and the edge 4R5 are joined to each other, the linear rubbers 4F1 and 4F2 and the linear rubbers 4R1 and 4R2 form a substantially annular stretchable member surrounding along the trunk opening 2T, and function to shrink the trunk opening 2T in the trunk-surrounding direction. That is, the linear rubbers 4F1 and 4F2 and the linear rubbers 4R1 and 4R2 exert contraction force to bring the diaper 1 into close contact with the wearer, thereby preventing a gap from being formed between the diaper 1 and the abdominal circumference of the wearer. A part of the plurality of linear rubbers 4F2 and 4R2 on the crotch region 1B side overlaps the absorber 8.

The linear rubbers 4F1 and 4R1 are provided so as to extend in the left-right direction along portions that are upper edges of the front body region 1F and the rear body region 1R shown in fig. 1. The linear rubbers 4F2, 4R2 are disposed in parallel at predetermined intervals. The linear rubbers 4F1 and 4R1 are strongly fastened to the abdominal circumference of the wearer at positions above the linear rubbers 4F2 and 4R2 in the state where the diaper 1 is worn. The linear rubbers 4F1 and 4R1 serve to prevent the diaper 1 from being put on the wearer by being brought into close contact with the wearer, thereby preventing displacement of the wearing position and leakage of discharged materials from the abdomen and back. The linear rubbers 4F2, 4R2 alleviate the sense of compression to the wearer caused by the contraction force of the linear rubbers 4F1, 4R 1. In addition, in the case of using the inner pad, the displacement of the inner pad is suppressed. The linear rubbers 4F1 and 4R1 are examples of the "1 st expansion member" described in the present application, and the linear rubbers 4F2 and 4R2 are examples of the "2 nd expansion member" described in the present application.

Further, the linear rubber 4F3 and the linear rubber 4R3 are bonded to the cover sheet 4. The linear rubbers 4F3 and 4R3 are expansion and contraction members provided in the cover sheet 4 in the region on the crotch region 1B side of the linear rubbers 4F2 and 4R 2. The linear rubber 4F3 provided in the front region (abdomen side) crosses the absorber 8 when viewed in the thickness direction. Here, in a region where the linear rubber 4F3 crosses the widthwise central portion of the diaper 1, the cover sheet 4 and the absorber 8 are non-bonded, and more specifically, in this region, the inner cover sheet 5 and the backsheet 6 are non-bonded. Therefore, the absorber 8 is not contracted by contraction of the linear rubber 4F3, and the cover sheet 4 can lift the absorber 8 toward the skin surface side. According to this configuration, the diaper 1 lifts the absorber 8 toward the wearer on the abdomen side, and the free ends of the three-dimensional gathers 3BL and 3BR are easily brought into contact with the wearer's skin at appropriate positions on the abdomen side of the wearer.

The linear rubber 4R3 is arranged to be bent in the direction of the crotch region 1B, unlike other linear rubbers which are continuously bonded from the left end to the right end of the cover sheet 4, and overlaps with a part of the core wrap sheet 7 at the contracted portion of the hourglass-shaped absorbent core 8 c. By disposing the linear rubbers 4F3, 4R3 so as to curve in the direction of the crotch region 1B, the disposed regions of the linear rubbers 4F3, 4R3 can be made to function as leg gathers 3LL, 3 LR. The linear rubbers 4F3 and 4R3 are examples of the "3 rd expansion member" described in the present application.

The cover sheet 4 is folded back at the folded-back lines 4FF and 4RF to extend to the arrangement regions of the linear rubbers 4F1 and 4R1, and the arrangement regions of the linear rubbers 4F1 and 4R1 are reinforced by the folded-back portions. The end pieces 11F, 11R are provided in the arrangement regions of the linear rubber 4F2 and the linear rubber 4R2 where the cover piece 4 folded back at the folding lines 4FF, 4RF does not extend, and reinforce the arrangement regions of the linear rubber 4F2 and the linear rubber 4R 2.

The state in which sheets overlap in the present application is not limited to a state in which sheets overlapping each other are overlapped with each other in a state of being in full contact with each other, but includes a concept in which a part of the sheets overlap with each other. For example, the number of the cells to be processed, a portion of the end piece 11F on one end side in the longitudinal direction of the back piece 6 overlaps with a portion of the cover piece 4 in a contact state. In the diaper 1, the cover sheet 4, the end sheets 11F, 11R, the inner cover sheet 5, and the side sheets 10L, 10R are stacked in addition to the back sheet 6 and the top sheet 9 sandwiching the absorber 8, and therefore, it can be said that a laminate in which these multiple sheets are stacked is provided.

Next, the bonding mode of the outer sheet of the diaper 1 according to the embodiment will be described with reference to fig. 4. Fig. 4 is a view schematically showing a state in which the diaper 1 of the embodiment is developed and extended. The diaper 1 has a cover sheet 4 forming an outer cover and an inner cover sheet 5 laminated on the skin surface side of the cover sheet 4 as outer cover. The cover sheet 4 and the inner cover sheet 5 are bonded by a plurality of bonding portions.

Specifically, the cover sheet 4 and the inner cover sheet 5 are bonded by a plurality of bonding portions 40F, 40R, 41F, 41R, 42F, 42R extending in the width direction of the diaper 1. These adhesive portions are formed of a hot melt adhesive. The plurality of bonding portions 40F are formed separately from each other. The plurality of bonding portions 40F are formed along the plurality of linear rubbers 4F1, respectively, and the linear rubbers 4F1 are bonded to the cover sheet 4 and the inner cover sheet 5 by the bonding portions 40F. The plurality of bonding portions 40R are formed separately from each other. The plurality of bonding portions 40R are formed along the plurality of linear rubbers 4R1, and the linear rubbers 4R1 are bonded to the cover sheet 4 and the inner cover sheet 5 by the bonding portions 40R. The plurality of bonding portions 40F are formed separately from each other. The linear rubbers 4F1, 4R1 are bonded to the cover sheet 4 and the inner cover sheet 5 in an elongated state, and form annular stretchable portions extending in the width direction of the diaper 1 in the trunk surrounding portion 2D.

The plurality of bonding portions 41F are formed separately from each other. The plurality of bonding portions 41F are formed along the plurality of linear rubbers 4F2, and the linear rubbers 4F2 are bonded to the cover sheet 4 and the inner cover sheet 5 by the bonding portions 41F. The plurality of bonding portions 41R are formed separately from each other. The plurality of bonding portions 41R are formed along the plurality of linear rubbers 4R2, and the linear rubbers 4R2 are bonded to the cover sheet 4 and the inner cover sheet 5 by the bonding portions 41R. The linear rubbers 4F2 and 4R2 are bonded to the cover sheet 4 and the inner cover sheet 5 in an elongated state, and form annular stretchable portions extending in the width direction of the diaper 1 in the trunk surrounding portion 2D. In the diaper 1, in the trunk surrounding portion 2D, the linear rubbers 4F1, 4R1, 4F2, 4R2 are bonded to the cover sheet 4 and the inner cover sheet 5 in an elongated state, thereby forming the waist gather 3R shown in fig. 1.

The plurality of bonding portions 42F are formed separately from each other. The adhesive portion 42F adheres the cover sheet 4 to the inner cover sheet 5 at a position closer to the crotch region 1B than the linear rubber 4F 2. The plurality of bonding portions 42R are formed separately from each other. The adhesive portion 42R adheres the cover sheet 4 to the inner cover sheet 5 at a position closer to the crotch region 1B than the linear rubber 4R 2. The adhesive portion 42F is disposed on the front body region 1F side from the longitudinal center of the diaper 1, and the adhesive portion 42R is disposed on the rear body region 1R side from the longitudinal center of the diaper 1. The bonding portions 42F and 42R bond the cover sheet 4 and the inner cover sheet 5 in a region where the linear rubber is not disposed between the cover sheet 4 and the inner cover sheet 5.

In the present embodiment, the absorbent core 8c has a shape narrowed in the width direction at the center in the longitudinal direction of the diaper 1. The region where the absorbent core 8c is narrowed in the width direction is a region corresponding to the crotch of the wearer, and is the crotch region 1B. Further, the widthwise end portions of the diaper 1 in the crotch region 1B extend in the longitudinal direction.

Here, the adhesive parts 40F, 40R, 41F, 41R, 42F, 42R extend linearly parallel to each other in the width direction of the diaper 1. Hereinafter, the bonding portions 40F, 40R, 41F, 41R, 42F, 42R may be collectively referred to as linear bonding portions 40F and the like. In order to bond the linear rubbers 4F1, 4F2, 4R1, 4R2, it is preferable that the bonding portion extends in the width direction. In order to make the feel of the trunk surrounding portion 2D and other portions uniform, a linear adhesive portion 40F or the like extending in the width direction is provided in the entire outer sheet.

When the cover sheet 4 and the inner cover sheet 5 are bonded over the entire area, the skin feel to the wearer is deteriorated because a hot melt adhesive is used for these bonding. The diaper 1 of the present embodiment includes the linear adhesive portions 40F and the like for adhering the cover sheet 4 to the inner cover sheet 5, and the cover sheet 4 and the inner cover sheet 5 are non-adhered between the linear adhesive portions 40F and the like, thereby suppressing deterioration of skin touch feeling to the wearer. Thus, the diaper 1 of the present embodiment can suppress a decrease in the wearing sensation.

In addition, when the shape of the bonded portion and the extending direction of the bonded portion are different in each region of the diaper 1, for example, in each of the arrangement regions of the linear rubbers 4F1, 4R1 and the arrangement regions of the linear rubbers 4F2, 4R2, the manner of approaching the wrinkles of the outer sheet is different depending on each region, and the appearance of the diaper is deteriorated. In contrast, since the direction in which the linear adhesive portion 40F or the like extends is the same throughout the entire region of the diaper 1 of the present embodiment, the manner of approaching the wrinkles of the outer cover sheet is uniform in each region, and the appearance is not impaired.

In addition, when the diaper 1 is divided into a plurality of regions in the longitudinal direction, the linear adhesive portions 40F and the like are equally spaced from each other in each region. For example, the diaper 1 can be divided into a region in which the linear rubbers 4F1 and 4R1 are arranged (an example of the "1 st region" in the present application), a region in which the linear rubbers 4F2 and 4R2 are arranged (an example of the "2 nd region" in the present application), and a region on the crotch side of the region in which the linear rubbers 4F2 and 4R2 are arranged (an example of the "3 rd region" in the present application). The 1 st region is a region close to the trunk opening edge forming the trunk opening 2T shown in fig. 1, and is a region where the linear rubbers 4F1, 4R1 are arranged. The 2 nd region is a region adjacent to the 1 st region on the crotch region 1B side, and the linear rubbers 4F2, 4R2 are arranged. The 3 rd region is a region adjacent to the 2 nd region on the crotch region 1B side, and a stretchable member such as a linear rubber extending in the width direction is not disposed between the cover sheet 4 and the inner cover sheet 5. The arrangement region of the linear rubber 4F3 crossing in the width direction is not included in the 3 rd region.

In the region where the linear rubbers 4F1, 4R1 are arranged, the respective intervals of the plurality of adhesion portions 40F, 40R are the same. In other words, the plurality of linear rubbers 4F1, 4R1 are arranged at equal intervals. In the region where the linear rubbers 4F2 and 4R2 are arranged, the respective intervals of the plurality of adhesion portions 41F and 41R are the same. In other words, the plurality of linear rubbers 4F2, 4R2 are arranged at equal intervals. In the crotch side region of the region where the linear rubbers 4F2, 4R2 are arranged, the respective intervals of the plurality of adhesion portions 42F, 42R are the same. Since the diaper 1 is designed to have different adhesive forces required for each region, the distance between the linear adhesive portions 40F and the like is made uniform for each region, whereby the change in the feel and appearance of the skin as a whole can be made uniform, and the excessive or insufficient adhesive force for each region can be prevented.

The distance between the adhesive parts 42F, 42R in the crotch side of the region where the linear rubbers 4F2, 4R2 are arranged is 3 times or less wider than the distance between the adhesive parts 40F, 40R in the region where the linear rubbers 4F1, 4R1 are arranged. Similarly, the distance between the bonding portions 42F and 42R in the crotch side region of the region where the linear rubbers 4F2 and 4R2 are arranged is 3 times or less wider than the distance between the bonding portions 41F and 41R in the region where the linear rubbers 4F2 and 4R2 are arranged. In short, the distance between the bonding portions 42F and 42R in the region where the linear rubbers are not arranged is 3 times or less wider than the distance between the bonding portions 40F and 40R and the distance between the bonding portions 41F and 41R in the region where the linear rubbers 4F1 and 4R1 and the linear rubbers 4F2 and 4R2 are arranged. Of the intervals between the bonding portions, the interval between the bonding portions 42F and 42R is the widest, the interval between the bonding portions 41L and 41R is the second widest, and the interval between the bonding portions 40L and 40R is the narrowest. With this configuration, the diaper 1 of the present embodiment can reduce the difference in skin feel and appearance between the areas where the linear rubbers are not disposed (the bonding portions 42F and 42R), the areas where the linear rubbers 4F2 and 4R2 are disposed (the bonding portions 41F and 41R), and the areas where the linear rubbers 4F1 and 4R1 are disposed (the bonding portions 40F and 40R). In the diaper 1, the interval between the bonded portions gradually increases from the edge of the trunk opening portion 2T to the crotch side, and the rigidity gradually decreases toward the crotch side, so that the skin feel can be softened. Further, by making the interval between the adhesive portions 42F, 42R the widest, making the interval between the adhesive portions 41L, 41R the second widest, and making the interval between the adhesive portions 40L, 40R the narrowest, the rigidity is improved in the vicinity of the trunk opening portion 2T, and the region where the linear rubbers 4F1, 4R1 are arranged is brought into relatively strong contact with the skin of the wearer, whereby the displacement of the trunk surrounding portion 2D in the wearing state can be prevented.

As described above, the distance between the adhesive parts 42F and 42R in the crotch side region of the region where the linear rubbers 4F2 and 4R2 are arranged is 3 times or less wider than the distance between the adhesive parts 41F and 41R in the region where the linear rubbers 4F2 and 4R2 are arranged. The crotch region 1B is particularly required to be breathable. The diaper 1 can reduce the areas of the bonded portions 41F and 41R to be non-breathable, thereby obtaining desired breathability.

Further, since the crotch region 1B of the diaper 1 is sandwiched between the thighs of the wearer, the end portion of the outer sheet is caught (bitten) into the thighs in the crotch region 1B. On the other hand, the front region 1F of the diaper 1 is positioned along the abdomen of the wearer, the rear region 1R of the diaper 1 is positioned along the buttocks and the back of the wearer, and the outer sheet does not sink into the skin of the wearer in the front region 1F and the rear region 1R. Therefore, in the crotch region 1B, if the end portion of the outer sheet in particular in the width direction is bonded over the whole surface, the end portion becomes hard and the skin touch is deteriorated, but in this portion, the bonded portions are separated from each other in the longitudinal direction, so that the skin touch can be made soft.

The diaper 1 further includes whole-surface adhesive portions 43FL, 43FR, 43RL, 43RR which are disposed adjacent to the adhesive portions 42F, 42R at the end portions in the width direction of the cover sheet 4 and the inner cover sheet 5, and which adhere the cover sheet 4 and the inner cover sheet 5 to each other on the extending lines in the width direction between the adhesive portions 42F, 42R. The entire surface adhesive portions 43FL, 43FR, 43RL, 43RR are formed by applying a hot melt adhesive to the entire surface of the formed regions. The whole-surface adhesive parts 43FL, 43FR, 43RL, 43RR are formed so as to avoid the crotch region 1B. Thus, the crotch region 1B is located between the whole-surface bonded portions 43FL and 43RL on the left side of the diaper 1, and the crotch region 1B is located between the whole-surface bonded portions 43FR and 43RR on the right side of the diaper 1. By configuring such that the crotch region 1B is sandwiched by the whole-surface adhesive portions when the diaper 1 is viewed in the longitudinal direction, the whole-surface adhesive portions 43FL, 43FR, 43RL, and 43RR function as beams with respect to the longitudinal direction of the diaper 1, and the crotch region 1B can be made less likely to contract.

The entire surface adhesive portions 43FL, 43FR, 43RL, 43RR are disposed at the end portions of the diaper 1 in the width direction. When the diaper 1 is viewed in the width direction, the linear adhesive portion 42F is disposed between the entire surface adhesive portion 43FL and the entire surface adhesive portion 43FR, and the linear adhesive portion 42R is disposed between the entire surface adhesive portion 43RL and the entire surface adhesive portion 43RR. By providing the whole-surface adhesive portions at both ends in the width direction of the diaper 1 in this manner, the widthwise central portion between the whole-surface adhesive portions can be made less likely to contract.

As shown in fig. 1, the diaper 1 includes a left lower limb opening 2L and a right lower limb opening 2R through which the lower limbs of the wearer are inserted. The lower limb opening edges 2KL, 2KR forming the lower limb openings 2L, 2R are formed to include the cover sheet 4 and the inner cover sheet 5. As shown in fig. 4, the whole surface adhesive parts 43FL and 43RL are formed along the lower limb opening edge 2KL to the lower limb opening edge 2KL. In the same way as described above, the whole surface adhesive parts 43FR, 43RR are formed along the lower limb opening edge 2KR to the lower limb opening edge 2KR. Accordingly, the entire adhesive portion can be provided on the lower limb opening end edges 2KL and 2KR of the portion extending in the oblique direction with respect to the longitudinal direction of the diaper 1, that is, on the lower limb opening end edges 2KL and 2KR other than the crotch region 1B, so that the non-adhesive region between the cover sheet 4 and the inner cover sheet 5 is not formed in a part. Thus, the skin feel at the widthwise end portion of the outer sheet can be made uniform over the entire area.

The linear rubbers 4F3, 4R3 are bonded to the cover sheet 4 and the inner cover sheet 5 by the whole-surface bonding portions 43FL, 43FR, 43RL, 43 RR. The linear rubbers 4F3, 4R3 extend from the crotch region 1B side of the side seals SL, SR along the lower limb opening end edges 2KL, 2KR. Leg gathers are formed by the linear rubbers 4F3, 4R3 to contract the lower limb opening portions 2L, 2R. In the present embodiment, the linear rubbers 4F3, 4R3 for forming leg gathers can be prevented from falling off by bonding the linear rubbers 4F3, 4R3 by the respective whole-surface bonding portions.

In the crotch region 1B, the adhesive portions 42F and 42R extend from the center in the width direction to both ends in the width direction of the diaper 1. In this way, the crotch region 1B bonds the cover sheet 4 and the inner cover sheet 5 not by the entire surface bonding portion but by the linear bonding portions 42F and 42R. Thereby, the diaper 1 can suppress a decrease in skin feel in the crotch region 1B.

Further, a whole-surface adhesive portion 44 is provided in the width-direction central portion on the front body region 1F side (the abdomen side) of the crotch region 1B so as to be continuous with the whole-surface adhesive portions 43FL and 43 RL. The whole-surface adhesive portion 44 includes a central portion crossing the width direction of the diaper 1 in an area corresponding to the pubic bone of the wearer. The entire surface adhesive portion 44 is formed of a hot melt adhesive, and the cover sheet 4 and the inner cover sheet 5 are adhered to each other in the same manner as the entire surface adhesive portions 43FL, 43RL, and 44 are integrally formed.

The region provided with the whole-surface bonding portion 44 has higher rigidity than the region provided with the linear bonding portion 40F or the like which is not whole-surface bonded. The diaper 1 of the present embodiment can improve the rigidity of the outer sheet on the abdomen side of the crotch portion by providing the whole-surface adhesive portion 44. The region where the whole-surface adhesive portion 44 is formed is a crotch adjacent region adjacent to the crotch, and a pubic bone corresponding region corresponding to the pubic bone of the wearer. Since the region where the whole-surface adhesive portion 44 is formed is higher in rigidity than other regions, even if the crotch region 1B is pinched by the thighs of the wearer and contracted in the width direction, the contraction is not transmitted to the front body region 1F side (abdomen side), and therefore, the reduction in the wearing feeling due to the contraction can be suppressed.

The entire surface bonding portion 44 includes a region where the linear rubber 4F3 crosses in the width direction, and bonds the linear rubber 4F3 to the cover sheet 4 and the inner cover sheet 5. Since the central portion in the width direction is pulled outward by the contraction force of the linear rubber 4F3, the contraction of the central portion in the width direction of the diaper 1 in the entire surface bonded portion 44 can be further suppressed.

The entire adhesive portions 43RL and 43RR are disposed on both sides with an anus corresponding region 45 corresponding to the anus of the wearer interposed therebetween. In other words, the entire surface adhesive portion for adhering the entire surface of the cover sheet 4 and the inner cover sheet 5 is not provided in the region corresponding to the anus of the wearer. By forming the whole-surface adhesive portions 43RL and 43RR so as to extend to both sides of the anus-corresponding region 45, both sides of the anus-corresponding region 45 can be made highly rigid, and the both sides can be made to follow the skin surface of the wearer, and the anus-corresponding region 45 can be made to be separated from the skin surface (anus) of the wearer. The anus-corresponding region 45 is a region corresponding to the anus of the wearer, and is also a region where feces discharged by the wearer stays. By separating the anus-corresponding region 45 from the skin surface, the diaper 1 can suppress the feces from being pressed against the skin of the wearer.

Further, since the linear rubbers 4R3 on the rear body region 1R side are not connected to each other at the linear rubbers 4R3 on both sides at the central portion in the width direction of the diaper 1, there is no expansion/contraction force at the central portion in the width direction. In other words, the linear rubber 4R3 does not extend to the anus-corresponding region 45, but extends over the entire region where the surface-bonded portions 43RL and 43RR are formed. Since the anus-corresponding region 45 is pulled outward by the contraction force of the linear rubber 4R3, the anus-corresponding region 45 can be further separated from the skin surface. The linear rubber 4R3 extends to a region overlapping the absorbent core 8c when viewed in the thickness direction. In the extension region of the linear rubber 4R3, since the inner cover sheet 5 is bonded to the back sheet 6, the linear rubber 4R3 and the absorbent core 8c are indirectly bonded via the inner cover sheet 5, the back sheet 6, and the core wrap sheet 7. Since the anus-corresponding region 45 is pulled outward by the contraction force of the linear rubber 4R3, the absorbent core 8c in the anus-corresponding region 45 can also be separated from the skin surface.

The diaper 1 further includes other stretchable members extending in a direction perpendicular to the linear adhesive portion 40F or the like when viewed in plan. The other stretchable members may be, for example, linear rubbers 10L1 and 10R1 for the three-dimensional gathers 3BL and 3BR shown in fig. 2, or linear rubbers separately provided between the cover sheet 4 and the inner cover sheet 5. When the linear adhesive portions 40F and the like extending in the width direction of the diaper 1 are provided at intervals in the longitudinal direction, the outer sheet is contracted in the longitudinal direction by the other stretchable members described above, and the folds extending in the width direction can be formed by the outer sheet located in the non-adhesive regions between the linear adhesive portions 40F and the like. Since the gathers are arranged in the entire area, the diaper 1 exhibits a uniform appearance. In addition, if the above-described other stretchable members are not provided, it is difficult to restrict the direction of the wrinkles of the outer sheet, and the absorbent body may be distorted due to the direction of the wrinkles, and the wearing feeling of the diaper 1 may be reduced. Since the diaper 1 of the present embodiment is provided with the other stretchable members described above, the deterioration of the wearing sensation can be suppressed.

The lower limb opening edges 2KL, 2KR have curves having a plurality of inflection points. At the inflection points of the leg opening edges 2KL and 2KR, the cutting direction of the cutter of the cutting device at the time of forming the leg openings 2L and 2R changes, and therefore the cover sheet 4 and the inner cover sheet 5 of the diaper 1 may be difficult to cut. In the present embodiment, the whole surface adhesive parts 43FL, 43FR, 43RL, 43RR are provided including inflection points of the lower limb opening edges 2KL, 2 KR. Thus, the cutting of the sheet along the lower limb opening end edges 2KL, 2KR is easily performed at the inflection point, and the formation regions of the lower limb opening portions 2L, 2R can be cut with high accuracy.

< modification >

Next, a diaper 1 according to a modification of the present embodiment will be described. Fig. 5 is an exploded perspective view of the diaper 1 of the present modification. In the diaper 1 of the present modification, the absorber 8 includes an absorbent core 8c composed of a plurality of pads and a core wrap 7 wrapping the absorbent core 8c. As shown in fig. 5, the absorbent core 8c has an upper absorbent pad 8a and a lower absorbent pad 8b. The upper layer absorbent pad 8a has a substantially hourglass shape with narrowed portions, and the lower layer absorbent pad 8b has a rectangular shape. The width of the lower absorbent pad 8b is substantially the same as the width of the narrowed portion of the upper absorbent pad 8 a. Thus, the absorbent core 8c may be constituted by 2 layers of pads.
